Summarizing and Q&A

Understanding Presentations Made By Other People

Copilot in PowerPoint isn't only for building decks — it's also useful when someone else has shared one with you. This is most valuable when the deck is long, dense, or covers a topic you don't already know well.

Two main features handle this: full-deck summaries and targeted questions about specific content.

Summarising An Entire Presentation

To get a quick overview, open any slide and click the shooting stars icon. From the dropdown, choose Summarize this presentation.

Copilot Chat opens on the right and generates a summary within seconds, usually structured as:

• Clear headings for the main topics;
• Short explanations of the key points;
• References to the original slides;
• A final overview paragraph of the whole deck.

That last detail — references to specific slides — is important. You can always jump back to verify what Copilot said against the actual source.

Asking Specific Questions

When something on a slide is unclear, you don't need to read every surrounding slide to figure it out — you can just ask Copilot directly in chat.

This works well for:

• Clarifying a difficult idea;
• Understanding the reasoning behind a point;
• Decoding technical content;
• Getting quick answers without manually searching slides.

Copilot uses the presentation as its source and usually points to the relevant slides in its answer.

Summary vs. Targeted Question

The two features serve different moments:

• A summary is for when you don't yet know what you're looking for and need the lay of the land;
• A targeted question is for when you already have a specific thing you need to understand.

In practice, you often use both — summary first to orient yourself, then targeted questions to dig into the parts that matter.
